Abstract
The utility model relates to a car anti-collision device which plays the role of buffer when cars are collided and guarantees life safety of people in the cars. The car anti-collision device comprises an automotive underpan. Oil cylinders are respectively fixedly arranged at the front portion and the back portion of the automotive underpan. Elastic anti-collision beams are fixedly arranged on the end faces of piston rods of the oil cylinders. The oil cylinders are connected with a hydraulic pressure station through oil tubes and oil valves. A signal control end of the hydraulic pressure station is connected with a control switch signal end through lines. The car anti-collision device has the advantages of being capable of effectively and slowly releasing impact force produced by collision of cars and maximally guaranteeing the life safety of the people in the cars, low in production cost of the anti-collision beams, convenient to replace and maintain and capable of greatly reducing cost of car repairing.
Description
Technical field
The utility model relates to a kind of buffer action that plays when car collision, guarantee the anti-collision device for automobile of occupant's life security, belongs to anti-collision device for automobile and makes the field.
Background technology
CN2767236Y, its engine flywheel of title " car chassis " are connected with power-transfer clutch by locating dowel pin and bolt, for eliminating noise, power-transfer clutch are redesigned.Driving engine, change speed gear box and part-time case link to each other with vehicle frame by bolt by the blob of viscose that suspends.The driving engine aft end face connects by bolt and clutch case simultaneously, and change speed gear box and part-time case are connected with clutch case by bolt.The mouth flange is connected with front propeller shaft by bolt before the part-time case, and the front propeller shaft other end is connected with propons main reduction gear method dish.Front propeller shaft adopts dual cardan type U-joint.The mouth flange links to each other by bolt and rear propeller shaft behind the part-time case, and the rear propeller shaft rear end links to each other with the rear-end gear reduction flange.Its weak point is: when car collision, can not well play the effect of buffering, easily jeopardize occupant's life security, cause casualties and property damage.
Summary of the invention
Design goal: avoid the weak point in the background technology, design a kind of buffer action that when car collision, plays, guarantee the anti-collision device for automobile of occupant's life security.
Design plan: in order to realize above-mentioned design goal, 1, the anterior respectively intrinsic oil cylinder of car chassis, the design of the intrinsic elastic anti-collision beam of piston rod end face of oil cylinder is one of technical characterictic of the present utility model.The purpose of doing like this is: because oil cylinder is connected with Hydraulic Station by oil pipe, fuel tap, Hydraulic Station signal control end connects the master cock signal end by line, before running car, make (the control of the controlled device of Hydraulic Station of startup Hydraulic Station by master cock, automatic operation, locking), Hydraulic Station makes the elastic anti-collision beam that is positioned at the oil cylinder piston rod end surface protruding under the effect of oil cylinder piston by oil pipe and control cock, in order to protect car body, with anticollision; When the moment that automobile contingency is clashed into; what impacted in the very first time is elastic anti-collision beam before and after the car body; the elastic anti-collision beam passes through the elasticity of itself in the slowly-releasing impact; the piston that is used for the support elastic collision prevention girders cushions impact again at hydraulic oil; thereby greatly reduced the impact of impact to car body, protection occupant life security.After the parking, by master cock and Hydraulic Station oil cylinder piston is retracted and reset, then close Hydraulic Station and get final product.2, the design of fuel tap pressure chip is two of technical characterictic of the present utility model.The purpose of doing like this is: because the compression resistance of pressure chip is set according to the slowly-releasing automobile impact force; therefore when bump occurs in automobile; its impact is during greater than the setting value of pressure chip; pressure chip is broken; hydraulic oil leaks; the oil cylinder piston decompression had both reached the purpose of protecting oil cylinder, reached again to prevent from clashing into bounce to the secondary injury of human body.
Technical scheme: a kind of anti-collision device for automobile, comprise car chassis, described car chassis is anterior, the intrinsic oil cylinder of rear portion difference, the intrinsic elastic anti-collision beam of the piston rod end face of oil cylinder, oil cylinder is connected with Hydraulic Station by oil pipe, fuel tap, and Hydraulic Station signal control end connects the master cock signal end by line.
The utility model is compared with background technology, and the one, the impact that effectively produces during the slowly-releasing auto against guarantees occupant's life security to greatest extent; The 2nd, elastic anti-collision beam cost of manufacture is low, be convenient to the maintenance of the side of replacing, greatly reduces the expense of repairing.
Description of drawings
Fig. 1 is the structural representation of anti-collision device for automobile.
